This is certainly the most interesting and evocative itinerary on the island. Along the old mule track, through a tunnel and through the thick Mediterranean scrub in Erica and Corbezzolo, you will arrive in Acciattore. This is where you'll find wild rosemary, Asfodelo and interesting Sardinian and Corsican endemisms.
If you turn around, you'll see a wonderful view of the small lake known as “Laghetto,” the only natural water basin in the Tuscan Archipelago. In the springtime, it’s covered in white ranunculus flowers. A small path along the coast leads to Monte Le Penne, which offers great views of Corsica and the other islands.
At this point, you’re 420m above sea level. Before reaching the rocky cliff of Penne there is a small path that leads from the western coast to the north: this is where the penal colony, the Sella dell'Acciattorela Colonia Penale Agricola, stood for a century.
A beautiful ring itinerary allows visitors to cross the thick and wild Mediterranean scrub to enjoy stunning views of the island. Across the wall that symbolically defined the area of the jail, the pathway leads downhill to the first Lavanderia. From there, the dirt road leads to the port.
